They asked about Watson for two reasons...
1) he was making noise demanding a trade. Basically everyone who didn't have Brady, Mahomes, Allen, Rodgers or Wilson was making a call to inquire. We did. Texans told everyone to kick rocks. Cool.
2) AFTER Brad Holmes took over the GM job, Stafford let it be known he'd like to move on and not go through another rebuild with another HC. They worked it out.
IMHO, Stafford was the MUCH better fit. He's maybe the perfect QB for McVay. He's nails in the 4th quarter, tougher than a $2 steak, has wicked high football IQ, and can make every throw from every angle.
That no look pass in the Super Bowl was so ballsy, Stafford could have one ball removed and STILL need a wheelbarrow to move his nut around...
The upside for Watson is his youth and raw talent. He's really good.
That said, I dunno that we win the Super Bowl with Watson.
